One call out - senior engineers at FB are a different breed and caliber altogether vs a “senior developer” at your typical insurance company or someone contracting AngularJS development in a senior role for an oil and gas company. People see the word senior and think it’s an apples to apples comparison. I’m not saying the FB engineers are “better”, but I am saying the level of ownership, design, code quality, etc is day and night different... an environment like FB, Amazon, Google etc will force you to become a great developer (rigorous code reviews, various levels or owning what you wrote, supporting your services, developing run books, etc etc. My 2 cents from my experience on both sides (working in non tech companies and big tech companies).
